Study reveals mixed impact of state e-cigarette flavor bans on tobacco use
2025-07-30
A new study by investigators from Mass General Brigham examined the effects of policies banning flavored e-cigarettes on adults and young people. Investigators found that e-cigarette use significantly declined among young adults and adults in states that had enacted flavor bans relative to states that did not. However, declines in cigarette smoking also slowed in those states with flavor bans relative to other states—a potential unintended consequence of the bans. Results are published in JAMA Network Open.

Most US adults have hearts older than their actual age. How old is yours?
2025-07-30
CHICAGO --- Most U.S. adults have a “heart age” several years older than their chronological age — sometimes by more than a decade. And that gap is wider among men and among those with lower incomes or education or who identify as Black or Hispanic, according to a new study led by Northwestern Medicine.
As part of the study, the Northwestern scientists created a free online tool that calculates a person’s “heart age” based on their risk for cardiovascular disease, using routine health data such as blood pressure, cholesterol levels and whether ...

The metabolic dialogue between intratumoral microbes and cancer: implications for immunotherapy
2025-07-30
The tumor microenvironment (TME) represents a highly complex system that encompasses cellular components (such as cancer cells, stromal cells, and immune cells) and non-cellular components (such as blood vessels and signaling molecules)[1-3]. These diverse components engage in complex interactions with tumor cells and undergo dynamic changes during tumor progression. Specifically, intratumoral microbial metabolites play an important role on the TME. The metabolic products of these microorganisms encompass a range of bioactive molecules, including lactate, amino acids, short-chain fatty acids (SCFAs), bile acids, trimethylamine N-oxide, and inosine. These metabolites, ...

Huge hidden flood bursts through the Greenland ice sheet surface
2025-07-30
A huge flood triggered by the rapid draining of a lake beneath the Greenland ice sheet occurred with such force that it fractured the ice above and burst out across its surface.
This phenomenon, observed for the first time in Greenland and detailed in research published today in the journal Nature Geoscience, sheds new light on the destructive potential of meltwater stored beneath the ice sheet.
It reveals how, under extreme conditions, water flooding underneath the ice can force its way upwards through the ice and escape at the ice sheet surface.
This phenomenon is not considered by numerical models ...
The brain shapes what we feel in real time
2025-07-30
The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has identified a mechanism by which certain thalamic projections target neurons and modify their excitability. This work, published in Nature Communications, reveals a previously unknown form of communication between two regions of the brain, the thalamus and the somatosensory cortex. It could explain why the same sensory stimulus does not always elicit the same sensation ...

Hydroquinone-buffered covalent organic frameworks for long-term photocatalytic hydrogen peroxide production
2025-07-30
Hydrogen peroxide (H₂O₂) is an essential eco-friendly oxidant, but its conventional anthraquinone-based production is energy-intensive and generates hazardous waste. Photocatalysis offers a sustainable, solar-driven alternative. Organic polymer photocatalysts, notably covalent organic frameworks (COFs), have gained attention due to their tunable structures, earth-abundant elements, and visible-light responsiveness. Although recent advances (e.g., polarity-optimized, fluorinated, or sulfone-containing COFs) have improved H₂O₂ yields and extended stability to 336 hours, long-term durability remains limited. Most systems exhibit reaction times of less than 200 hours ...
